Parámetros genéticos de la longitud de panícula en arroz
The investigation was carried out during 2007 and 2008 in two location of the Department del Valle del Cauca. Two contrasting progenitors were evaluated (long panicle: FL1028 and short: Norin 22) and the generations F1, F2, RC11 and RC21. The used design was randomized complete blocks with four repl...

| description | The investigation was carried out during 2007 and 2008 in two location of the Department del Valle del Cauca. Two contrasting progenitors were evaluated (long panicle: FL1028 and short: Norin 22) and the generations F1, F2, RC11 and RC21. The used design was randomized complete blocks with four replications. The variance analysis for the variable: panicle length, number of primary ramifications per panicle, number of secondary ramifications per panicle, number of branches per plant, number of panicle per plant, percentage of sterility showed significant differences (p<0.01) between generations. In CIAT the total genetic variance was 95% to the additive variance; in Jamundí in 68%. They were positive and significant correlations in both locations among panicle length and the variables number of primary and secondary ramifications, percentage of sterility and weight of a thousand grains; negative and significant for number of branches per plant and panicle number per plant with regard to the panicle length. The panicle length with relationship to percentage of sterility in Jamundí showed non significant correlation. |

La investigación se realizó durante 2007 y 2008 en dos localidades del Valle del Cauca, Colombia. Se evaluaron dos progenitores contrastantes (panícula larga: FL1028 y corta: Norin 22) y las generaciones F1, F2, RC11 y RC21. Se utilizó el diseño de bloques completos al azar con cuatro repeticiones. El análisis de varianza mostró diferencias significativas (p<0.01) entre generaciones para las variables: longitud de panícula, número de ramificaciones primarias por panícula, número de ramificaciones secundarias por panícula, número de macollas por planta, número de panículas por planta, porcentaje de esterilidad. En la localidad CIAT la varianza genética total se debió en 95% a la varianza aditiva; en Jamundí en 68%. Se encontraron correlaciones positivas y significativas en ambas localidades entre longitud de panícula y los caracteres número de ramificaciones primarias y secundarias, porcentaje de esterilidad y peso de mil granos; negativas y significativas para número de macollas por planta y número de panículas por planta con respecto a la longitud de panícula. La longitud de panícula con relación a porcentaje de esterilidad en Jamundí mostró correlación no significativa. 2008 2014-10-02T08:33:39Z 2014-10-02T08:33:39Z Journal Article https://hdl.handle.net/10568/44362 es Open Access |
